The following document contains practice problem sets (and solutions) that are similar to the problems normally found in midterm and final examinations. The problems for Chapters 13, 14, 15 (up to and including XML Schema) are suitable for the midterm. The rest -- chapters 10, 11, 15 (from XPath and on), 16, 17 -- are for the final exam. Some midterm-style problems may also appear in the final examination.
First try to solve the problems by yourself. Then compare your solutions with the ones provided.
